It is bordered by the communities of; Rhosddu, and Caia Park to the north, Abenbury to the east, Esclusham, and Marchwiel to the south, and Broughton, Coedpoeth, and Gwersyllt to the west.

According to Howard Williams and Liam Delaney, a Professor of Archaeology and Doctoral Researcher respectively, at the University of Chester, the area is named after Bryn Offa (Welsh for Offa's Hill), a housing estate and former hall located currently within the community.

Williams and Delaney state that such distinction between the two dykes was only made by the nineteenth century at earliest.

It was first established only in April 1985, after a boundary review bought four new 'urban' communities into being within the then town of Wrexham.

The Community Council states that it was noted in a Welsh Assembly report as one of the most "active and innovative" in Wales.
